linux default iconStreamCruncher Publisher's description

StreamCruncher is an Event Processor.

StreamCruncher is an Event Processor. The project supports a language based on SQL which allows you to define Event Processing constructs like Sliding Windows, Time Based Windows, Partitions and Aggregates.

Queries can be written using this language, which are used to monitor streams of incoming Events. StreamCruncher is a multi-threaded Kernel that runs on Java.

Ever since RFID became commercially viable and companies started packaging their entire product line as Business Activity Monitoring Stacks, an old idea that has been around for almost a decade is now seeing the light of day. A handful of Startups have begun turning this Idea of Complex Event Processing (CEP) and Event Stream Processing (ESP) into Commercial grade software. Several people have contributed ideas to this field. The most frequently mentioned name would be Prof. Luckham's. Prof. Widom's contribution to the field is also noteworthy.

Those in a hurry can skip to this section.

Now, back to CEP and ESP. An over-simplified definition would probably look like this - Assume that a System produces "Events" that describe the state of that System at those instants. Slicing and Dicing the "live" Stream of Events (in near real-time) can reveal vital information. Since this information is available on the live data and not stale data, it can be used to look for Warning signs, implement JIT materials sourcing, Automated Trading and other highly nimble systems.

Events from multiple sources can be co-related to reveal information about their interactions and dependencies. CEP and ESP are not exactly the same, but we'll leave that to the Scholarly Papers to disambiguate. All this does not seem new at all to people who've been working on Control Systems. Data Warehouse specialists and Rule Engine experts might start mumbling something about "Old Wine..".

However, only lately are we seeing generic, off-the-shelf Software focusing on CEP and ESP. Each one of those Products or Projects distinguish themselves
